Description

This model uses

  • d3q27 cumulant collision kernel for hydrodynamics
  • d3q7 cascaded collision kernel for heat
  • Boussinesq approx to couple heat with hydrodynamics

BC

  • periodic
  • Dirichlet - Equilibrium scheme (1st order convergence)
  • Dirichlet - Anti Bounce Back (2nd order convergence)
  • Dirichlet - Interpolated Anti Bounce Back (2nd order convergence)
  • Neumann like bc - impose heat flux

  • WVelocity inlet

  • EPressure Outlet
  • Neumann Outlet
  • Convective Outlet
